  • Patent number: 7296504
    Abstract: The technical field of the invention is that of pyrotechnic actuators comprising a piston, the basic function of which is to exert a thrust so as to displace an object by shooting out the piston. More particularly, the invention relates to a pyrotechnic actuator (1, 1a, 1b, 1c) comprising a pyrotechnic-gas generator (7), a combustion chamber (3) and a piston (9) which can move in a slide chamber (5) under the effect of the said gases. The principal characteristic of this actuator is that it comprises a shut-off device (4, 4a, 4b, 4c) used after the triggering of the said actuator (1, 1a, 1b, 1c) in order, on the one hand, to close the slide chamber (5) and, on the other hand, to secure the depressurization of the combustion chamber (3).

  • Patent number: 7281346
    Abstract: A portable gun support case having gun support members firmly held in place on the case by retaining members attached to the case. The case has a lower box and an upper box which includes two longitudinal box or cover sections pivotally mounted on the lower box. When the box is open, the support members may be placed in upright positions adjacent walls of the lower box. The retaining members then may be moved into firm holding engagement with the support members. When the support members are removed from their upright positions, the upper box may be pivotally closed above the lower box along a center line formed by the two longitudinal cover sections and in engagement with the lower box. When the upper box engages the lower box, outward projections at opposite ends of the upper box are engaged by the retaining members to hold the case firmly closed.

  • Patent number: 7182013
    Abstract: An umbilical cord retractor assembly and method is provided for retracting an umbilical cord from a torpedo or other vehicle prior to launching the vehicle. A guide arm is utilized to guide a slide member along a predetermined path within the guide arm. The slide is connected through a link to the umbilical cord such that the umbilical cord is pulled to a predetermined position within the launch tube out of the way of the fins, shroud, and propeller of the vehicle. Prior to activation of the retractor assembly, the slide is affixed in position within the guide arm by a lock. A spring under tension applies a force to the slide. A release cord pulls a pin from the slide to release the cord at a desired time, thereby retracting the umbilical cord to the predetermined position within the launch tube.

  • Patent number: H2182
    Abstract: Provided is an unleaded gasoline fuel which is substantially free of oxygenates, and most preferably contains substantially zero oxygenates. The gasoline fuel also has a Reid vapor pressure less then 7.5 psi, a sulfur content less than 30 ppmw, an aromatic hydrocarbon content between 25 and 30 volume percent, and/or a 50% D-86 Distillation Temperature between 210 and 220° F., and/or a 90% D-86 Distillation Temperature between 300 and 330° F., and the fuel composition fails the California Predictive Model requirements for emissions. Preferably, the olefin content of the fuel is also 8 volume percent or less. Such a gasoline fuel offers a substantially oxygenate free gasoline which avoids the environmental impact of oxygenates, yet when combusted in an internal combustion automobile provides good performance and good emissions, despite failing the California Predictive Model. The gasoline fuel in particular can provide surprisingly lower NOx emissions than that predicted by the California Predictive Model.

  • Patent number: H2228
    Abstract: A conductivity sensor positioned in-line between two pipe sections within a cylindrical collar portion of a measurement assembly measures the electrical conductivity of fluid under flow through a passage therein to generate a conductivity data signal, while a separate temperature measurement data signal is generated by a temperature sensor embedded within the collar portion of the measurement assembly in close axially spaced relation to the conductivity sensor. Both of the data signals are fed from the conductivity and the temperature sensors to a data processing system to provide a temperature compensated conductivity measurement readout.
